Abstract (en)

[origin: US2002126534A1] A circuit produces a voltage for the erasure or programming of a memory cell. The circuit includes a capacitor, and a discharge circuit connected to a first terminal of the capacitor. The discharge circuit includes a first transistor, a drain of which is connected to the first terminal of the capacitor. The first transistor activates the discharge circuit when a discharge signal is received by a gate of the first transistor. The discharge circuit includes a slow discharge arm and a fast discharge arm parallel-connected to the source of the first transistor. The discharge circuit produces a low discharge current or a high discharge current for discharging the capacitor as a function of an operating mode selection signal.
